I am just gutting the interior of a 1976-1978 Americo F-16.
I was able to salvage most extruded aluminum cabinet doors and commode door.
Windows are plastic not sure if that is original, however extruded window frames will be available when removed.
I have what may be the original sink and faucet.
Also original cushions if needed for a pattern or for original material reference.
Please inquire about anyting else not much was left.
